My research interests lie in pure mathematics as broadly defined. At heart, I am a problem solver. My drive to prove theorems and understand mathematical relationships has taken me to the boundaries and intersections of algebra, analysis, combinatorics, computer science, dynamical systems, fractal geometry, number theory and probability. For more information about me and my research activities please see the following links:

I am Deputy Editor-in-Chief of the Journal of the Australian Mathematical Society. For paper submissions and further information see this link.

Documenta Mathematica has recently published my co-edited book,
with Michael Baake (Bielefeld, Germany) and Yann Bugeaud (Strasbourg, France):
